Multiply .800 moles of O2 by Avagadro's number divided by 1 mole. This will get rid of the moles on the bottom and leave you with molecules. So technically .800 times 6.02x10^23.
Answer:
8J
Explanation:
From the question, the gravitational stored energy is 8J.
So Mgh=8J.
The kinetic energy is ?
When we use the law of conservation of energy, as the apple is moving and about to it the ground, it has 0m speed.
Which means that the potential energy at rest i.e when the apple is on the ground is zero. When the apple is getting to the ground, KE +PE is conserves.
At the top of the tree, the Apple has zero potential energy because velocity is zero at rest and on hitting the ground, the apple has kinetic energy.
So, the maximum Kinetic energy is 8J.
Answer: The final pressure is 116kPa or ![116kN/m^2](https://tex.z-dn.net/?f=116kN%2Fm%5E2)
Explanation:
The combined gas equation is,
where,
= initial pressure of gas =
= final pressure of gas = ?
= initial volume of gas = v ml
= final volume of gas =
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The final pressure is 116kPa or
Answer: Atomic Mass
Explanation:
The Atomic mass of an atom is the number of protons and neutrons in the atom and is measured in atomic mass units (amu) but can still be measured in kilograms.
For example, if the number of neutrons in an atom is 8 and the number of protons is 6, the atomic mass of the atom is 14.
